That when you tested the coil like that it doesn't mean the spark is getting to the distributor, it just means that the coil is capable of putting out spark. Checked to see if any problems on computer mother boards. The spark should travel from the rotor to the cap down the wires to the plugs. So working back to eliminate the distributor I pulled the primary from the coil to the distributor and still no spark. New ignition wires. If not, a good place to start would be new points, condenser and rotor. The high performance electronics repair kit. A bad ignition coil (on engines that have a distributor and a single coil) A bad rotor or distributor cap (cracks or carbon tracks that are allowing the spark to short to ground) A faulty ignition switch. If the coil sparks you need to head to the TCI and check wires, the red white wire at the TCI should have +12 volts. the CDI, and send it to the spark plug. Without them your engine will turn over but wonât start. Hence, without this high voltage, there is no spark and, consequently, internal combustion cannot take place within the engine. Tried new cap and new rotor, new cap old rotor, old cap new rotor, old cap old rotor. Pull Your Crank Sensor And Make Sure Its Free Of Debris Check the attached links,instruction and guides, Good luck. Got fuel. Ford F-150 1997 4.6l xlt 220000 miles.

White bEAR laKE, Minnesota. Troubleshooting: Primary Coil: Check for 0.1 ohm ~ 1.0 ohm across the two primary coil terminals. The black wire is ground. High voltage is then generated in the coil windings. He began his writing career writing curriculum and lectures in automotive mechanics at New York Technical Institute. Examine the battery, ignition switch and circuitry if the coil primary voltage is errant or not present at all. Finally, checking the fuel injectors using a noid light revealed No flashing with the noid light. There are a few reasons for no spark, new coil pack could be defective, crank sensor, ignition module or bad wire in primary circuit, faulty ECM/PCM. Or even a screwdriver in the end of the coil. Car is getting fuel, turns over but no spark at all from coil. I have no spark. So I decided to take it around the block the car turned off and would not start.. Older ignition systems used breaker points to interrupt the circuit, while more modern systems "sense" the need for spark by means of a hall-effect switch or crankshaft position sensor. 190 0. Have power to coil but no spark. Bad ground connections have the same effect as any open circuit, and battery and engine grounds should not be overlooked when diagnosing a "no spark" condition. High voltage is then generated in the coil windings. 2003 CBR600RR No Spark, No Power to Coil. Mark helpful. Power confirmed to the coil.
